An elevator exerts a force of 8000 N to lift the passengers 15 m. How much work is the elevator doing?
2 answers:
Answer:
120,000 J
Explanation:
The work done by a force applied parallel to an object is given by:
where
F is the magnitude of the force applied
d is the displacement of the object
In this problem:
F = 8000 N is the force exerted by the elevator to lift the passenger
d = 15 m is the displacement of the elevator
Therefore, the work done in this situation is
So, the work done is 120,000 J.
